President elect Donald Trump is pro-business and anti-red tape. But what if your business is red tape?

Companies whose technology helps banks and investors cope with the welter of post financial crisis regulations and avoid increasingly hefty fines - a sector known as "regtech" - are sanguine about Trump's pledge to dismantle some of those reforms.

Their equanimity is based on a belief that if regulations are replaced rather than scrapped and the overall system of rules becomes more fragmented, financial firms will need their systems to navigate the new landscape.

"Change is itself a driver of regtech adoption," said David Buxton, the chief executive of compliance startup Arachnys. "Volatility creates opportunity for relatively nimble regtech firms."

Founded in London in 2010, Arachnys helps financial services firms carry out anti-money laundering and other compliance checks by automating the analysis of more than 16,000 public and private sources of data. It's one of a growing cohort of mostly private companies that use new digital technologies, such as cloud computing and big data processing, to help financial institutions comply with regulation ranging from rules on trading conduct to know-your-customer procedures.

Despite the results of the U.S. election and expectations that the new administration will take a softer stance on the enforcement of financial rules, Arachnys is moving forward with U.S. expansion plans and renting out bigger office space in midtown Manhattan.

"The top 10 deals that my sales team are currently focused on, not one single one has voiced any concerns about 'wait and see' in the regulatory environment," Buxton, who is currently based in New York, said.

Regtech companies such as Arachnys have become the new darlings of the private investment world as financial firms are expected to accelerate their spending on compliance technology to $72 billion by 2019 from $50.1 billion in 2015, according to research firm Celent.

Venture capitalists have invested $2.3 billion in regtech start-ups globally since 2012, according to data provider CB Insights. Funding volume is expected to drop 2% this year to $576 million compared to 2015, but activity is expected to grow 15% to 90 deals, according to CB Insights.

Lots of assistance needed

Trump has said he wants to dismantle the Dodd-Frank Act, a massive piece of reform legislation passed by the Obama administration in 2010 in response to the financial crisis, though he has not detailed how he would fulfill that pledge.

Members of the incoming administration have pinpointed the law's Volcker rule, which bans banks from making speculative bets with deposit-insured funds, as one that needs changing and a rule protecting retirement savers, set to be rolled out in April, as one that should be torn up.

"If the landscape changes yet again, even if the direction of travel is towards lighter regulation, banks will still need lots of assistance understanding the new regimes and updating their systems and processes accordingly," said Angus McLean, a partner at law firm Simmons & Simmons.

And financial firms will always want to cut costs, regardless of who is in the White House.

The use of artificial intelligence, cloud computing and big data processing to automate many of banks' most labor intensive compliance functions - from listening to hours of phone call recordings to spot misconduct to going through hundreds of spreadsheets to calculate an institutions exposure to risk - is still a big draw.

"Using next generation technology to uncover, structure, analyze and action customer data to reduce risks for the business is an imperative that will flourish regardless of government," said Lex Sokolin, the global director of fintech strategy at research house Autonomous Research.

To be sure, if incoming rules are scrapped without new regulations introduced to replace them, then regtech firms whose business is based around them could see customer orders and their own funding dry up. For example, companies that sell software exclusively focused on helping a bulge bracket bank keep track of risk and trading metrics that would trigger the Volcker rule.

"Any uncertainty around deadlines or indeed outright implementation can only serve to confuse the end user and hence have a slowing impact on adoption," said Mark Beeston, a managing partner at fintech venture capital firm Illuminate Financial Management.

Others note that not all regtech might be safe. Pascal Bouvier, a venture partner at Santander Innoventures, the corporate venture capital arm of Spanish banking group Santander, believes that scrutiny on lenders could weaken if the new administration decides to rein in the Consumer Financial Protection Bureau, of which the Republicans have been fierce critics.

"If there is less scrutiny on lending practices, then lenders have less incentive to adopt regtech solution that help them be compliant," Bouvier said.

Financial fragmentation

If Trump succeeds in rolling back financial legislation or eases up on its enforcement, it will accelerate a trend towards regulatory fragmentation globally.

Within the European Union, some Eastern European countries and smaller states are opposed to international agreements on bank rulebooks. Britain's decision to leave the European Union, meanwhile, has thrown into questions global banks' future ability to base themselves in London, the region's financial capital.

These regtech companies should be able to benefit from competing regimes, offering tailored products to deal with them.

"While the global institutions will govern themselves by the most restrictive rules to limit exposure to those most restrictive rules, there will be efforts to explore regulatory arbitrage within investment strategies that once again will need to be informed by regtech offerings," said Terry Roche, head of fintech research at Tabb Group.

More demand for regtech products is also coming from regulators and policy makers, who are also on the hunt for more efficient ways to carry out their functions.

Certain financial ground rules, including stamping out insider trading and stopping money laundering, are here to stay. Companies focused on those activities, such as London-based trade surveillance software provider Behavox, see no impediment to future growth.

"We are still progressing with our expansion to the USA and in fact I am moving to USA permanently as we see more opportunities and a larger market in the USA," said Erkin Adylov, Behavox's chief executive.
